The nav.h was missing for ground_alt in the ms5611 driver, added that to 
v4.2. Also changed the default I2C address to match a low CSB\ as most 
boards (Aspirin2.1, FreeIMU 0.4.3, ...) have that pin low.

You add i2c0 by having USE_I2C0 in your airframe file.

<target name="ap" board="<your_board_type>">
      <define name="USE_I2C0"/>
      ...
